IMPROVEMENT IN BURR-BOX FOR BURRING-MACHINES.

Specification forming part of Letters-Patent No. 56,257, dated July 10, 1866.

.To all whom it may concern:

Beit known that I, ZIBA PAEKHUEST, of Milford, in the county of Vorcester and State of Massachusetts, have invented an Improved Burr Receiver or Box for either Double or Single Burring-Machines, or other machines ot' like character; and I do hereby declare the same to be fully described in the following specitication and represented in the accompari yin g drawings, of which- Figure 1 is a top view, and Fig. 2 a vertical section, ofthe said invention.

The common burr box or receiverI of a burring-machine is to catch the burrs or waste matters discharged from the wool or fibrous material operated on by the machine. Aconsiderable portion of the ibrous material is liable to be' thrown into the box with the burrs, and it is the purpose of Iny improvement to prevent such, and to cause the said tibrous material, or much of it, at least, to be separated from the burrs and to fall back into the machine while the burrs are being driven into the box or receiver.

In carrying out my invention I apply to the burr-box one or more guards or vertical strips of metal or other suitable material, so arranged as to intercept the bers so that they may fall down upon one or more cylinders of the machine, so as to be again worked over by such.

In the drawings, A is the box, and B C are two of the said guards, a'third or horizontal bar or guard being shown at D. These guards extend from end to end of the box, and each oi' the vertical ones may be so applied thereto as to be capable of being moved up or down more or less, and of being fixed or held in position, or they may be immovably ixed to the ends, if preferable. To the front part of the bottom of the said box I apply a curved lip, E, to extend somewhat over'the upper one of the two feed-rollers, and to prevent the burrs and extraneous matters from falling back upon it, as well as to guide them into the box.

The waste iibrous material, by being thrown against the guard or guards, will be estopped thereby, and will fall therefrom back into the machine, the burrs passing on into the box.

rEhe top guard, D, answers two purposesviz., as a brace or connection to the projecting parts of the ends of the box, and as a means of intercepting the waste filaments of the material, which may be thrown upward, in order that, by the action of gravity, they may be caused to fall back upon or into the machine.

I would remark that my invention is applicable to those machines by which wool or other ibrous matter is deprived of burrs.

I do not claim a burr-box as commonly made; but

I claim as my inventionl. The improved burr receiver or box as provided with one or more guards, B C D, whether stationary or adjustable, and arranged substantially as hereinbeiore described, the same being to arrest the waste filaments of fibrous material, so that they may be caused to fall back upon the burring-machine while the burrs or foreign matters are in the act of being discharged into the box.

Z. The combination and arrangement of the lip E with the box and its guard or guards, as specified.
